What It Is

This is a pre-wound replacement bump head spool assembly for EGO Power+ 15-inch string trimmers. It holds 17 feet of 0.095-inch trimmer line and replaces the OEM head without needing to disassemble or wind line yourself.

Fitment & Compatibility

Check your model number – this fits EGO Power+ 15” models ST1500, ST1500F, ST1500-S, ST1500SF, and ST1500XY only. It will not fit 16” or 18” EGO trimmers or any other brand. The head uses a standard left-hand thread shaft—confirm your trimmer has a metal shaft with this thread pattern. If your trimmer has a different line diameter (e.g., 0.080” or 0.105”), this head won’t match the cutting performance or may jam. Measure your existing spool diameter: this replacement is 3.5 inches wide. If your original is larger or smaller, the guard clearance may be off.

Key Things to Know

• Pre-wound saves time – no winding or measuring line. The 0.095” line is thicker than standard 0.080”, so it’s better for heavy weeds but may bog on lighter grass.
• Bump-feed mechanism can be finicky – some users report the head doesn’t advance line reliably on the first bump. Tap firmly on grass, not pavement.
• Installation is simple – remove the old head (turn clockwise), screw this one on hand-tight. No tools needed. But if your trimmer has a locking pin, use it to hold the shaft.
• Durability is average – the plastic housing may crack if you hit curbs or rocks. Consider a metal head if you do heavy edging.

Should You Buy It

If you own one of the listed EGO 15” models and want a quick, no-wind replacement, this is a decent budget option. But at $18.69 and a 3.7-star rating, it’s a compromise—you get convenience over reliability. Better for occasional trimming than daily commercial use. If you’re willing to wind your own line, buy the OEM head for ~$25 for more consistent performance.
